Starlink, the satellite-based internet service provider, is rapidly gaining global popularity. This subsidiary of Elon Musk’s SpaceX is delivering internet services worldwide through thousands of satellites. In regions where optical fiber is difficult or impossible to deploy, Starlink can easily provide high-speed internet using electromagnetic waves from its satellites.

What is Starlink and How Does it Work?

Starlink is a constellation of satellites owned by SpaceX that provides internet service through thousands of artificial satellites positioned in low Earth orbit (approximately 550 kilometers above the Earth). Conventional internet transmits data via optical fibers or cables, whereas Starlink does so directly through satellites. Geostationary satellites, located much higher from Earth (around 35,786 kilometers), transmit data, which results in slower speeds and higher latency (the time it takes for data to travel). However, Starlink’s satellites are much closer to Earth, allowing data to travel faster, thus providing high speed and low latency.

The Starlink project began in 2015, with its official launch in 2019. As of January 30, 2025, approximately 6,994 Starlink satellites have been deployed. These satellites orbit about 342 miles (550 kilometers) above Earth, capable of delivering high-speed internet service to the entire world.

Advantages and Reasons for Starlink’s Popularity

Starlink’s primary advantage is its ability to deliver high-speed internet to remote areas. It has revolutionized connectivity in regions where traditional internet infrastructure is unavailable. This has significantly eased communication for education, healthcare, and during natural disasters. Currently, it operates in over 100 countries, with Bhutan being the first country in South Asia to launch Starlink services.

Starlink’s internet download speeds typically range from 25 to 220 Mbps (megabytes per second), though most users experience speeds exceeding 100 Mbps. Upload speeds usually fall between 5 and 20 Mbps. These high speeds and low latency make it ideal for online gaming, video calls, and high-definition streaming.

While its service can be expensive and speeds might decrease slightly during adverse weather, Starlink’s unparalleled service in remote areas has made it globally popular. It is expected that future satellite deployments will further improve its speed and coverage.
